the sudden escape of gas or liquid confined under pressure, such as in a gas or oil well, or in a system containing pressurized air or steam.
An unexpected violent eruption of oil and gas from a well during the drilling phase of operation. This happens when high pressure gas is encountered and the proper precautions have not been taken. The initial eruption is followed by an uncontrolled flow of fluids from the well.
an uncontrolled flow of gas, oil, or other well fluids into the atmosphere or into an underground formation. A blowout, or gusher, can occur when formation pressure exceeds the pressure applied to it by the column of drilling fluid.
An uncontrolled flow of pressurized wellbore fluids and/or formation fluids from the wellbore or into lower pressured subsurface zones (underground blowout). A blowout occurs when formation pressure is greater than the pressure applied to it by the column of fluids in the wellbore.
Uncontrolled gas and/or oil pressure and eruption from a well.
An uncontrolled flow of gas, oil, or other fluids from a well into the air. A well may blow out when pressure deep in the reservoir exceeds the weight of the column of drilling fluid inside the well hole.
n: an uncontrolled flow of gas, oil, or other well fluids from the well.
A sudden escape of oil or gas from a well, caused by uncontrolled high pressure. It usually occurs during drilling.
Uncontrolled or uncontrollable release of down-hole pressure upward through the well-bore or casing.
Out-of-control gas or oil pressure erupting from a well.
occurs when internal pressure tends to push the gasket material out from between flanges. Blowout usually occurs in areas of low flange pressure and high internal pressure.
Uncontrolled flow of gas, oil, or other well fluids from a well during drilling due to formation pressure exceeding the pressure exerted by the column of drilling mud.
Uncontrolled or uncontrollable release of downhole pressure upward through the well-bore or casing. Although the main danger is fire, the gases are also toxic, and in floating operations a gas blowout may include a threat to the stability of the rig itself. (See Mud)
when downhole pressure overcomes the weight of drilling fluid and rises in a well to the surface out of control. An underground blowout is where the overpressuring enters another formation higher in the well, but before it reaches the surface.
Term used when the ready-mixed concrete breaks through the forming boards due to insufficient bracing. Also, the localized buckling or breaking up of rigid pavement as a result of excessive longitudinal pressure. See ready-mixed concrete.
A sudden, uncontrolled flow of drilling fluid, oil, gas, or water from a wellbore when the formation pressure in a permeable formation exceeds the pressure in the borehole. A kick sometimes warns of low pressure in the borehole.
A blowout is the uncontrolled release of a formation fluid, usually gas, from a well being drilled, typically for petroleum production. A blowout is caused when a combination of well control systems fail—primarily drilling mud hydrostatics and blow-out preventers (BOPs)—and formation pore pressure is greater than the wellbore pressure at depth. When such an incident occurs, formation fluids begin to flow into the wellbore and up the annulus and/or inside the drill pipe, and is commonly called a kick.
